If f(–5) = 0, what are all the factors of the function ? Use the Remainder Theorem.
a. (x – 2)(x + 5)(x – 3)
b. (x + 2)(x – 5)(x + 3)
c. (x – 2)(x + 5)
d. (x + 2)(x – 5)

Answer:

y - 3 = 5(x + 1)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

here m = 5 and (a, b) = (- 1, 3), hence

y - 3 = 5(x - (- 1)), that is

y - 3 = 5(x + 1) ← in point- slope form

[tex]y=2x^2\\\\\text{exchange x to y and vice versa:}\\\\x=2y^2\\\\\text{solve for y:}\\\\2y^2=x\qquad\text{divide both sides by 2}\\\\y^2=\dfrac{x}{2}\to y=\sqrt{\dfrac{x}{2}}[/tex]

Answer:

D. [tex]x=2y^2[/tex]

Step-by-step explanation:

We have been given an equation [tex]y=2x^2[/tex]. We are asked to choose the equation that could be solved to get the inverse of given equation.

We know that to find the inverse of a function, we interchange the x and y variables and then we solve for y.

Upon interchanging x and y variables in our given equation, we will get:

[tex]x=2y^2[/tex]

Therefore, the equation [tex]x=2y^2[/tex] can be simplified to find the inverse of our given equation and option D is the correct choice.

Answer:

35 degrees

Step-by-step explanation:

This is because the angles on the same line are supplementary meaning that they add up to 180 degrees.  This means that the two angles which are not x are 180 - 90 = 90 degrees and 180 - 125 = 55 degrees.  Since the angles in a triangle are also supplementary as well, then 180 - 90 - 55 = 35 degrees.

Please mark for Brainliest!! :D Thanks!!

For any questions or more information, please comment below and I'll respond as soon as possible.

Answer:

35°

Step-by-step explanation:

Angles on a straight line add up to 180°

The angle opposite 90° will be 90° because

180° - 90° = 90°

The angle opposite 125° will be 55° because

180° - 125° = 55°

So now we know that 2 of the 3 angles sum to 145° ( 55° + 90° ), we have to work out p so

180° - ( 55° + 90° ) = 180° - 145° = 35

Answer:

340/3

Step-by-step explanation:

1 yard = 3 feet.

To find out how many yards 340 feet is, divide 340 by 3.

So, your answer is 340/3.

Answer:

Part 1) see the procedure

Part 2) [tex]4.95x+49.95 < 9.95 x[/tex]

Part 3) [tex]x > 9.99\ months[/tex]

Part 4) The minimum number of months, that he needs to keep the website for site A to be less expensive than site B is 10 months

Step-by-step explanation:

Part 1) Define a variable for the situation.

Let

x ------> the number of months

y ----> the total cost monthly for website hosting

Part 2) Write an inequality that represents the situation.

we know that

Site A

[tex]y=4.95x+49.95[/tex]

Site B

[tex]y=9.95x[/tex]

The inequality that represent this situation is

[tex]4.95x+49.95 < 9.95 x[/tex]

Part 3) Solve the inequality to find out how many months he needs to keep the website for Site A to be less expensive than Site B

[tex]4.95x+49.95 < 9.95 x[/tex]

Subtract 4.95x both sides

[tex]4.95x+49.95-4.95x < 9.95 x-4.95x[/tex]

[tex]49.95 < 5x[/tex]

Divide by 5 both sides

[tex]49.95/5 < 5x/5[/tex]

[tex]9.99 < x[/tex]

Rewrite

[tex]x > 9.99\ months[/tex]

Part 4) describe how many months he needs to keep the website for Site A to be less expensive than Site B.

The minimum number of months, that he needs to keep the website for site A to be less expensive than site B is 10 months

To make Site A less expensive than Site B, James needs to host his website there for at least 10 months.

Let's define m as the number of months James would host his website. We write an inequality that represents the situation: $4.95m + $49.95 <= $9.95m. This represents the total cost of Site A being less than or equal to Site B.

To solve the inequality, subtract $4.95m from both sides of the equation: $49.95 <= $5m. Dividing both sides by 5 gives: m >= 9.99, which we round up to 10 because we can't have a fraction of a month.

So, James would need to keep his website hosted on Site A for at least 10 months to be less expensive than Site B.

Answer:

3/-2

Step-by-step explanation:

(3x) km/3 -2x=4 (x3) times 3 on both sides because you need to get the x by itself and your dividing so the opposite of dividing is multiplying.

9km - 2x = 12

-9               -9 subtract on both sides

Answer:

Solution of the given equation: [tex]x=4 , -7[/tex]

Step-by-step explanation:

An equation is a mathematical statement that states that two things are equal to each other.

A linear equation in one variable is of the form [tex]ax^2+bx+c=0[/tex] where a,b,c are coefficients and x is variable .

Here. given: [tex](x-2)(x+5)=18[/tex]

Using rule (Multiplication is distributive over addition) : [tex]a(b+c)=ab+ac[/tex] ,

we can write this equation as,

[tex](x-2)(x+5) =18\\ x(x+5)-2(x+5) =18\\ x^2+5x-2x-10 =18\\ x^2+3x-10-18 =0\\ x^2+3x-28 =0\\[/tex]

Answer:

The probability of choosing a black card then a white card, without

replacement is 24/91

Step-by-step explanation:

* Lets explain how to solve the problem

- There is a box contain some cards

- There are 8 white cards in the box

- There are 6 black cards in the box

- Two cards are choosing from the box a black card and then a white

 card, without replacement

∵ The number of the white cards in the box is 8

∵ The number of the black cards in the box is 6

∴ The total number of the cards in the box = 8 + 6 = 14

- We will chose the first card which is a black card

- We have 6 choices from 14 choices

∵ The number of the black cards is 6

∵ The total number of the cards is 14

∴ P(black) = 6/14 = 3/7

- Now the number of the black cards is 5 and the total number of the

 cards is 13 because there is no replacement

- We will chose the second card which is a white card

- We have 8 choices from 13 choices

∵ The number of the white cards is 8

∵ The total number of the cards is 13

∴ P(white) = 8/13

- Lets find the probability of choosing a black card then a white card

∵ P(black) = 3/7 and P(white) = 8/13

∴ P(black and white) = 3/7 × 8/13 = 24/91

* The probability of choosing a black card then a white card, without

  replacement is 24/91

The sum of -2 and -18 is -20.

When you add two negative numbers together, you're essentially combining their magnitudes while keeping the negative sign. In this case, you're adding the magnitudes of 2 and 18, which equals 20, and since both numbers are negative, the sum retains the negative sign. So, -2 plus -18 equals -20.

The complementary angle for 45 degrees is 45 degrees.

Given,

An angle = 45 degree

We need to find the measure of a complementary angle.

When the sum of two angles is 90 degrees the angles are called complementary angles.

Find complementary angles of 45 degrees.

Let. x be the complementary angle for 45 degrees.

x + 45 = 90

Subtracting 45 on both sides

x = 90 - 45

x = 45 degrees

We see that the required complementary angle is 45 degrees

Thus the complementary angle for 45 degrees is 45 degrees.

Answer:

sqrt(80)

sqrt(18)

sqrt(12)

Step-by-step explanation:

sqrt(196) = 14 which is rational.

7/18 is a fraction. There is nothing the matter with it. It is rational.

sqrt(80) = sqrt(16 * 5) = sqrt(4*4* 5) = 4 sqrt(5) which is irrational.

sqrt(18) = sqrt(9*2) = sqrt(3*3*2) = 3*sqrt(2) which is irrational.

sqrt(12) = 2sqrt(3) which is irrational

Rule: if there is anything left under the root sign then the starting number is irrational.

Answer:

Area of circle R = 75π un² or ≈235.5 un²

Step-by-step explanation:

The problem says that m∠TRS = 120º. The total number of degrees in a circle is 360º. 120º is a third of 360º. Therefore, we can prove that the shaded sector is a third of the circle.

The problem then says that the area of the shaded sector is 25π and we have to calculate the area of the entire circle. Since we already know that the shaded sector is a third of the circle, we can simply multiply 25π by 3 in order to calculate the area of t he entire circle.

25π × 3 = 75π.

Area of circle R = 75π un² or ≈235.5 un²

Answer: 75

Step-by-step explanation:

If the measure of TRS is 120, that is 1/3 the total of 360. Meaning the area of the shaded part is 1/3 the area of the full circle. If the area of the shaded part is 25, that means 25 is 1/3 the full area. the equation for that can be (25 = 1/3x) with x being the full area of the circle.

To solve just multiply both sides by the reciprocal of 1/3, which is 3.

25 x 3 = 75, which is your answer.

Step-by-step explanation:

right triangle is usually 45°45°90°

given angles: 90°and 32°

90+32=122

then 180-122=58°

Taking the sum of the three interior angles of a triangle and the definition of a right triangle, you get that the value of the other angle is 58°.

The right triangle is a geometric figure that is considered as a polygon formed by three sides that form a right angle and two acute angles. That is, a right triangle is one that has an interior angle that is right, that is, it measures 90º.

On the other hand, the sum of the three interior angles of a triangle is equal to 180 °.  Being α, β and γ the interior angles of the triangle, then:

α + β + γ= 180°

Being a right angle, whose value is 90 °, and another angle whose value is 32 °, it is replaced:

90° + 32° + γ= 180°

and solving you get:

122° + γ=180°

γ= 180° - 122°

γ= 58°

Then, the value of the other angle is 58°.

Answer:

No x-intercept.

Step-by-step explanation:

The zeroes are not real so it will not pass through the x axis.

Answer:

The correct option is A) No x-intercepts.

Step-by-step explanation:

Consider the provided information.

Nature of solution based on the value of discriminant :

If D = b² − 4ac > 0 then there exist two Real Solutions or roots.

If D = b² − 4ac = 0 then there exist one Real Solutions or roots.

If D = b² − 4ac < 0 then there exist no Real Solutions or roots

Here, we need to remember that the root of an equation and x-intercepts are the same thing.

Now consider the provided information.

The graph of an equation with a negative discriminant means:

D = b² − 4ac < 0

From the above values of discriminant we can say, there exist no Real roots or no x-intercepts.

Thus, the correct option is A) No x-intercepts.
